I am going to invest in a drenching gun for the goats specifically, for example if you have a goat with pregnancy toxeamia and have to drench several times a day.... I find goats are much more difficult to drench than sheep.... and are much more theatrical in showing their distaste of the whole process...
I was told to fill the gun in between uses with vegetable oil???
PLums - remember most wormers (not sure about ivermectin ones though, but definitely for Panacur/white or the yellow ones) need 1.5 to 1.7 times the sheep dose for worners.
